Re: st: RE: bootstraping with qreg bsqreg and sqreg
Dear Nick, thanks for your response.
I dont know if I should conclude that it is because of the randomness
that we expect. For example for one of the variable I am getting a std error
of .1238498 in method 2 but .0903295 in method 3 which is causing a shift
in p value from 0.101 to 0.025. Is that strange? If we are to take a
decision on the significance of a coefficient based on the P-value which
p-value (among the three we get) should we accept?
